闲话不提，下面直入正题，看备节点建功立业：
1，以修改之后的参数文件为优秀代表，启动备节点数据库到nomount模式下：
SQL> startup nomount pfile='/arch/initstandby.ora';
ORACLE instance started.
Total System Global Area 1073741824 bytes
Fixed Size 1999192 bytes
Variable Size 264244904 bytes
Database Buffers 805306368 bytes
Redo Buffers 2191360 bytes
2，创建服务器参数文件并关闭数据库：
SQL> create spfile from pfile='/arch/initstandby.ora';
File created.
SQL> shutdown immediate;
ORA-01507: database not mounted
ORACLE instance shut down.
3，启动修改后的监听（只需要修改其中的IP地址即可）：
$ lsnrctl start

4，启动数据库到mount下：
$ sqlplus "/ as sysdba"
SQL*Plus: Release 10.2.0.1.0 - Production on Fri Sep 11 15:54:55 2009
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Connected to an idle instance.
SQL> startup mount;
ORACLE instance started.
Total System Global Area 1073741824 bytes
Fixed Size 1999192 bytes
Variable Size 264244904 bytes
Database Buffers 805306368 bytes
Redo Buffers 2191360 bytes
Database mounted.
5，测试以网络方式注册数据库没有问题：
$ sqlplus as sysdba
SQL*Plus: Release 10.2.0.1.0 - Production on Fri Sep 11 15:01:20 2009
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options
SQL>
6，启动主节点数据库：
$ sqlplus "/ as sysdba"
SQL*Plus: Release 10.2.0.1.0 - Production on Fri Sep 11 15:59:29 2009
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options
SQL> alter database open;
Database altered.
7，重新关闭备节点数据库并以standby方式启动到mount状态下：
SQL> startup nomount
ORACLE instance started.
Total System Global Area 1073741824 bytes
Fixed Size 1999192 bytes
Variable Size 264244904 bytes
Database Buffers 805306368 bytes
Redo Buffers 2191360 bytes
SQL> alter database mount standby database;
Database altered.
8，将备节点更改到接受主节点redo日志模式下：
SQL> alter database recover managed standby database disconnect from session;
Database altered.
9，查看切换状态：
SQL> select switchover_status from v$database;
SWITCHOVER_STATUS
--------------------
TO PRIMARY
如果显示为TO PRIMARY，表示一切正常。
到此为止，备节点革命过程完毕，和主节点遥相呼应，要想完全接收主节点redo日志，就需要主节点做出一些动作了，连同主备切换放到下篇再说。
